Game of Thrones is filled with secrets that not a lot of people know about. Let us introduce you to some of them...Peter Dinklage was the one that recommend Lena Headey for the role of Cersei. George Martin tested David Benioff and D.B. Weiss with the question of who Jon Snow’s mother is when they were pitching the idea to adapt his beloved series. It is not explained much in the t.v. series but the Stark children can presumably all warg, not only Bran. Jon Snow’s death is different in the books in that the circumstance leading to it was different. They killed him because he broke his oath, not because he was accepting of the Wildlings. The First Men, The Andals, and The Rhoynar, were three separate groups of men that inhabited Westeros in the early years coming from different places. Catelyn Stark survives in the books after finding Beric Dondarrion and ends up killing Lannister’s and Frey’s. Tywin Lannister ends up foreshadowing a lot in the show. First, he is seen skinning the carcass of a stag, and then catches fish right before the Red Wedding. Ned Stark and Robert Baratheon were fostered as children by Jon Arryn which is how they became great friends. The conversation between Bran and Littlefinger during season 7 goes all the way back to Season 3 when Littlefinger and Varys were having a conversation. Jon Snow is the offspring of Rhaegar Targaryen and Lyanna Stark which makes him viable for the Iron Throne. Well, did you know any of these secrets? There are bound to be more as the season progresses on.
